Gibberella fujikuroi is a type of fungus that primarily affects plants, especially rice. It is known for causing a disease called "bakanae," which leads to elongated and weak stems in infected plants. This can result in reduced crop yields, making it a significant concern for farmers. The fungus produces a toxin called gibberellin, which disrupts normal plant growth. Interestingly, this same compound is used in agriculture to promote growth in various crops. Understanding Gibberella fujikuroi is essential for developing effective strategies to manage its impact on crops like rice and ensure food security.
